Stoop, this is Turkey. Last week after reading the new SGK law, the Fethiye Pro Consul said he couldn't make head nor tail of it, he then went on to say that the staff in the SGK office were also unclear on the detail. They are sending out letters offering people the option of opting out of SGK but are not sure if that is actually possible.
I won't loose sleep at the thought of them trying to establish my NI Contributions via the NHS and neither do I believe that the NHS have the time, inclination and ability to provide such info.
